Abstract

A polyether-ether-ketone (PEEK) high-voltage flexible DC transmission optical fiber composite extruded cable belongs to the technical field of wire and cable production. Metal conductors are arrangedin the center. The metal conductors are sequentially and concentrically coated with a conductor shielding layer, an insulating layer, an insulation shielding layer, a stainless steel pipe protected optical fiber layer, a semi-conductive buffer water blocking layer, a metal sheath layer, a nonmetal outer sheath layer, and a nonmetal conductive layer. A PEEK heat conducting and insulating, PEEK semi-conductive and PEEK conductive composite material is used as the material of the cable, and thus, a high-voltage flexible DC transmission optical fiber composite extruded cable all made of a PEEK material is constituted. The working temperature of the cable is increased, and high transmission capacity is achieved.

Description

technical field [0001] The invention belongs to the technical field of wire and cable production. Background technique [0002] The electric power industry is a basic industry related to the national economy and the people's livelihood. my country's economy continues to develop rapidly, people's living standards continue to improve, and energy demand grows rapidly. my country's power system needs to build UHV, long-distance, large-capacity, and low-loss power transmission channels. Power cables put forward higher requirements. At present, most of the power transmission cables in my country are AC extruded insulated cables, and with the continuous improvement of the operating voltage level, high-voltage flexible DC cables need to be used to solve the problem of long-distance cross-river, cross-river, cross-tourist scenic spots and megacities in China. The problem of power transmission corridors, and meet the power transmission needs of my country's offshore platforms and offsh...
